The Skills & Certifications tab identifies your skill sets and certifications associated with you. Unlike legacy specialties, skills and certifications are set at the person level rather than the Profile level. Using skills and certifications at the person level eliminates the need to manage separate profiles for changes made to a person’s specialty.
Using the skills and certifications section simplifies managing and maintenance of specialties by allowing greater effective date flexibility, and multiple same as specialties in one Setup area.
Security permission settings in Setup control the ability to view, edit or create new profiles, or both.
